No, it's not recommended for coding; it's a display font, to be used for headlines, titles, and the like, things where you want a little bit of stylistic flair. Here's the description from the link:

  About

  Space Mono is an original fixed-width type family designed by Colophon 
  Foundry for Google Design. It supports a Latin Extended glyph set, 
  enabling typesetting for English and other Western European languages.

  Developed for editorial use in headline and display typography, the 
  letterforms infuse a geometric foundation and grotesque details with 
  qualities often found in headline typefaces of the 1960s (See: 
  Microgramma[1], Eurostile[2]), many of which have since been co-opted by 
  science fiction films, television, and literature.

  Typographic features include old-style figures, superscript and subscript 
  numerals, fractions, center-height and cap-height currency symbols, 
  directional arrows, and multiple stylistic alternates.

I've been using Monaco for years. Something about it is very pleasing to me. However, I'm sort of bored with it and haven't been able to find a suitable replacement.
